Here, we investigate ground use of wild, unprovisioned black-and-white snub-nosed monkeys Rhinopithecus bieti by means of the scan sampling method. The results show that the monkeys spent 15.0% of the day time on the ground; 16.6%, 12.7%, and 15.6% for adult males, adult females and juveniles, respectively. Adult males and juveniles of both sexes showed significantly higher rates of terrestrial time than adult females. Females without clinging infants spent significantly more time on the ground than expected, while females with clinging infants spent significantly less time on the ground than expected. These results suggest that the higher degree of terrestrial behavior for males and juveniles may be due to their higher agility in comparison with females. Our study showed that the monkeys fed more on lichens relative to other food items when in the trees, but more on buds/leaves, flowers, fruits/nuts, resin/bark, and herbs when on the ground. According to our investigation, the ecological significance of the species＇ terrestriality lies mainly in the utilization of terrestrial food resources [ Current Zoology 55 （3） ： 180 - 187, 2009].展开更多

For the entire human history, cross-cultural communication is not strange. It plays an important role in studying different languages. Language is the carrier of culture and the main manifestation of culture. Language is developing with the development of a nation, it is an integral part of national culture, history, customs and local customs and practices, the nation＇s culture and social customs are also in the national language to show. The different historical background and development process leads to great difference exists in Western languages. With mutual understanding and deepen, the conflict in western culture are increasing. Language is the primary from of communication. And the use of language and culture are closely related. So ＂differences between Chinese culture and Western culture in English language＂ has become the important topic of intercultural communication.展开更多
